Membrane : 100.0% Rubber - Isobutylene Isoprene Rubber (IIR) - Butyl
Our inner tubes are tested continually by our professional teams, such as the U-19 Pro Racing Team and the MTB Racing Team.
To guarantee optimal quality, 100% of our inner tubes are inflated for a period of 8 hours.
Carry your inner tubes in a container to protect them from getting punctured (tool case, original packaging, etc.).
Wheel size is printed on the sidewall of your tyre. Always have a spare inner tube and a pump.
